Replace all amdsbs.sys files with the version from the Development Preview (you will need to change permissions/take ownership of files:
MountDir\Windows\System32\Drivers
MountDir\Windows\Winsxs
MountDir\Windows\System32\Driverstore\FileRepository

Dism /Unmount-Wim /MountDir:D:\Mount /Commit (I had to kill explorer.exe to do this as it kept locking the file)

Did this for both Install.wim and Boot.wim, no bluescreen on AMD RAID/AHCI now.

I have an SSD as well as a RAID 1 set up (physically 3 drives).
On my mobo I have the AMD SB850.

To have this run I have my bios set to RAID.

I installed Win8 on my SSD and it ran perfectly for about 2 weeks... No hassles what so ever!

Then all of a sudden I was shutting down my Win7 (also on SSD (Duel boot)) and I got a BSOD due to hd errors on my raid set up (I am aware of this and solving) But since then I havent been able to use WinFish (8) while in RAID mode. I boot and instantly get
the driver_irql_not_less_or_equal amdsbs.sys SFOD (Sad Face of Death). I even now get this when I boot off the disk! Ive formated off WinFish (8) and restored the Win7 BCD,

I don't get this at all! If it is a driver issue how did it work in the past?! I had no problems at all!

I also don't understand why the disk will Blue Screen.

If I change to IDE mode it will work fine,

I'm just so confused!

I tried the method above but I have no access to the Developers Preview drivers. If anyone can link these I would be very appreciative. If anyone can also explain to me what happened! I thought I understood computer but this one has got me so bad.

I don't know if it helps any, but I did install Windows 8 x64, both CP and RP, on the newer AMD Hudson D3 APU chipset while having RAID enabled in the UEFI BIOS.

Not only that but I did it on a RAID 1 mirror as a GPT disk. This machine is dual boot with Windows 7. Before I installed either, I configured, partitioned and formatted the mirror using WinPE from the Install media. I might have had to
load a driver in WinPE, but I had taken care of that by including a folder with the install drivers in it.

I used diskpart to clean and convert the "disk" gpt. I created the EFI partition and formatted it with fat32. Then I created and formatted with ntfs two smaller data partitions for my Windows versions and the rest in an additional data partition.
I installed Windows 7 and then Windows 8 RP. I was able to boot and use either OS from the Windows 8 Boot Manager, but I had to use bcdedit a lot to get it the way I wanted.

The Windows 8 installer makes it harder to get to the WinPE command prompt but you can get there from "Troubleshooting". When I tried to upgrade CP to RP it told me I could not keep any files, programs or settings but that it would put everything
in Windows.old. I let it continue with a fresh install of the CP on the same partition. I can still boot Windows 7 or the Windows 8 CP. I just cannot use Windows 7 because of a display corruption problem in the AMD driver.

I tried to update the same machine to boot from a SSD, but use the same RAID mirror for data. Windows 7 works fine since I fixed the display corruption. I get a WEI of 6.9.

Windows 8 x64 RP on the other hand has caused me much distress. I can't run it, not even safe mode, without a BSOD. I get either IRQL_NOT_LESS_OR_EQUAL or SYSTEM_SERVICE_EXCEPTION, always in amdsbs.sys.

On a different Windows 8 system, working on AMD Hudson D2, I have found some clues. The AMD RAID driver, ahcix64s, is installed with BOOT_START. Amdsbs has been changed from 0 BOOT_START to 3 DEMAND_START. This has been done by adding the
subkey StartOverride, with value "0" = 0x3, under HKLM\SYSTEM\CCS\Services\amdsbs. This is done instead of "Start" being changed to 0x3. I do not know if I can change the registry of the problem system to produce the desired result, but it
is worth a try.

You can use 7zip to pull files from a .wim file. The amdsbs.sys in the Consumer Preview is 3.7.1540.27 while the version in the Release Preview is 3.7.1540.30. The latest amdsbs.sys in Windows 7 is 3.6.1540.127.

I am still beating my head against this on my AMD A75 (Hudson D3) system. I want to get Windows 8 x64 to boot from an SSD but be able to use the mirror that is also mounted. Windows 7 x64 can do this with no problems. My latest fresh
install still chokes on amdsbs.sys. Next I will try some substitution.

My first attempt came up with INACCESSIBLE_BOOT_DEVICE. So I looked at the registry. I tried modifying the entries related to amdsbs, but even though I added HKLM\System\DriverDataBase\DriverPackages\amd64_amdsbs.inf_bc052695a65f7665 and changed
the settings in HKLM\System\DriverDataBase\DriverInfFiles\amdsbs.inf to match the replacement amd64_amdsbs.inf_bc052695a65f7665, it came up with UNABLE_TO_VERIFY_DRIVER_SIGNATURE, or something like that. I either missed something or I don't really know
what I am doing. Probably the latter.
